UTP HydroCav - UTP Schweissmaterial

Standards :
Material-No.. : Special alloy
DIN 8555 : W/MSG 3-GZ-55-ST
EN 14700 : S Fe8
Copper coated wire for highly wear resistant
build-ups on hot and cold working
tools
Application field
UTP A 73 G 2 is used for highly wear resistant buildups on machine parts and tools, subject to heavy abrasion
and compression combined with moderate impact at elevated temperatures, such as forging tools,
roll mandrils, hot trimming knives, mangle and axial rolls as well as for the production of high-quality working
surfaces by cladding non- or low-alloy base material.
Properties of the weld metal
Machinable by grinding or with tungstene carbide tools
Hardness of the pure weld deposit :
untreated 53 - 58 HRC
soft-annealed 820° C approx. 200 HB
hardened 1050° C/oil approx. 258 HRC
tempered 600° C approx. 253 HRC
1 layer on non-alloyed steel approx. 245 HRC

Welding instruction
Clean welding area to metallic bright. Cracks in the base material have to be gouged out completely. Preheating
temperature of 400° C on tools should be maintained. Stress relief, if necessary, at 550° C.
